This limits the part to indoor, temperature-controlled equipment — benchtop instruments, lab gear, office peripherals, and similar environments. It is not specified for industrial or automotive temperature extremes.
There is no end-of-life notice on record.
No, the MAX522CPA+ requires an external reference voltage. The reference type is External, so the board design must provide a clean reference source for the output full-scale voltage.
Yes. The digital supply range is 2.7V to 5.5V, so at 3.3V the SPI inputs are directly compatible with 3.3V logic levels without additional level translation.
Within the same family, the MAX522CPA+ is the through-hole PDIP variant. The surface-mount equivalent is the MAX522CSA+ (SOIC-8). Both share the same 8-bit dual DAC core, SPI interface, and supply range, differing only in package and temperature grade (the CSA+ is also 0°C to 70°C).
